@stryker when running prime95 open cpu-z and watch the voltage reading at idle and at load. you may have to further tweak llc setting.
after googling your motherboard, a lot of people are having troubles with vcore fluctuation, some run llc at 19% (ASUS M4A785TD-V EVO and M4A785TD-M EVO AM3 Motherboards Review - Page 18) whereas some found a more stable overclock at 0% llc. ([Solved] CPU Over Voltage Asus M4A785TD-V Evo/US36), and some suggest llc 38% (M4A785TD-V EVO wild voltage fluctuation range)

That is absolutely correct!my board's vcore fluctuates too even with the latest bios update
thanks for the links.will hava look at it first

glad you got it stable. looking at your post of 4.4ghz i was like:shock:
then seen the pic and found out that its 4.04ghz. cheers:mrgreen: now play some games like battlefield bad company 2, crysis, crysis 2 with dx11 patch and high res textures. if it crashes you may have to tweak your voltage or drop your clocks a bit.

4.4ghz or 4.04ghz :lol:....doesn't matter as i have been stuck on 3.8ghz and didn't have a clue to proceed further
but thanks to you guys' assistance + a lil' effort n patience from my side:wink:
i have achieved my target of 4.0ghz mark.

thank you once again :-D

Guwahati effect on OC temps lol...32 Deg Idle. Mine Does at 46 Deg thanks to 38 Deg Ambient. Going to try push it to 4.5 Ghz

@StrYker_BLACK_E,
hey buddy 1.525 is too much on air.don't go beyond 1.5v on air that too for 24X7.better stop it at 1.45-1.475v not more than that.btw try to bump your NB speed bit by bit and see if you can go further with v core strictly below 1.5v.i read somewhere that NB speed affects hugely on the processor speed and stability but i forgot ok here it is.give it a complete read.
btw i was able to get my 955 stable 4.2Ghz @ 1.45v temp was around 60C under load but now running at 3.2 @ 1.25v with load temp at 47-48GHz for 1 hr prime 95 testing.btw one more thing there is no need of running prime 95 for 8hr only one hour is more than enough.none of your daily applications will stress your processor that much as prime 95 do.

gosh!!i went off the limit @1.525 temp@63
i checked my cpu specifications on amd website and guess what
maximum temps@62
AMD Processors for Desktops: AMD Phenom?, AMD Athlon? FX, AMD Athlon? X2 Dual-Core, AMD Athlon?, and AMD Sempron? Processor

will start from the beginning.
thanks for the link and your advise.

btw p95 was not run for 8hrs only around 50mins. it was a typo by me too.should have type as 50mins instead of 5hrs:-D

In the zone
ur temps are fine the 62 deg C temps ure seeing are off by around 5-10 deg C..

also 62 deg C is probably core temp limit not package temp limit... coz ive myself done 84 deg C on package and have seen people doing upto 79 deg C... ur fyn... ur temp when reported 62 must be around 55 deg C... This temp reading is from probe under the socket...

Disable ACC - this won't aid in your OCing anyway - this is only needed to unlock cores on some specific cpus only.

I am running Stable @ 4.2GHz with all settings at defaults.

Only change is Multi to 20.5 & vCore @1.5v :D

Temps I am getting are 38-44 Deg Idle (Depending upon time of day)

And I am also using 212 EVO. So there is still head room of 200 Mhz for you to catch up :p

After 2 hrs of gaming it goes to 56-58 Deg. So I am happy with it.
